Well, I got the Remington Number 4 home today, I took the action apart which needed a pretty good cleaning, the rifling is excellent in this gun, I have ordered a couple of brass casings from Dixie Gun Works that are reloadable and can't wait to at least try and see what that's like when I shoot it.
I also found what was keeping the loading block from coming down all the way, it was nothing more than a burr on the top of the hammer. A few passes with an India stone and the gun works perfectly.
